SIZING'AND SHAPING MACHINE.

Application led May 20, v1925. Serial No. 31,598.

l This invention relates to a vsizing and shaping'machine and particularly to a sizing-and shaping machine for composite vtire grommets. I y. An object of the `invention resides in providing a sizingV and shaping machine for a composite grommet structure in which suitable sizing and shaping members are movably mounted on a plate member4 in cooperative relation for engaging the grommet to be shaped, which are operable by suitable means to effect the fixing and' shape of the size of the grommet.

A further object of the inventionresides in providing Ya sizing andshaping machine of the abovementioned character having a plurality of pairs of cooperating' shaping elements operable on a plate member by suitable operating means movable in a plane at right angles to the plate member having connection withY each of the shaping members of a pair for operating the sameina predetermined mannerr to elect the sizing and shaping. of composite ring structures.v

The invention includes other objects and improvements in the details of construction and arrangement of 'partswhich are more particularly pointed out in the following description and claims directed to a preferred form of the invention, it being understood, however7 that various changes may be made Yin the manner of mounting the cooperating fingers for operation on the plate member and the manner of operatingthesame through the operating means, without departing from the spirit and scope of the invention as herein set forth.

In the vdrawing forming part of this ap-` plication, y F ig. 1 is a plan view of the structure forming the subjectv matter of the invention7 Fig. 2 is avertical sectional' view taken on the line 2-2`oic Fig. `1, and n n Fig is a detail perspective view of a ring `member clamped in the proper size and shape resulting from the operation of the machine thereon. Y

A `plateymember is indicated at 1 which is of annular form having a central opening 2 and a plurality of radial slots 3 opening through the outer periphery of the member. The member throughout the length of these slots andat the side portion thereoftis chanerence to the drawing, it will be understood neled as indicated at ll for receiving and shdably mounting the inner and outer cooperating ingers 5 and 6, respectively, havmg. guide projections 7 slid-ably ,mounted in. the channels 4. The plate member is suitably supported in a horizontalfposition by legs vSas clearly shown in Figs. 1 and 2. The periphery of the plate member is also formed at predetermined points ywith recesses 9 which have a purpose to be presently described.

A base plate .is indicated at 10 provided with a boss 11 in which is mounted the standard l2 extending upwardly therefrom substantialy in axial alignement with the axis of the plate member land provides a slidable mounting for the sleeve 13 of the op- 70 erating means for t-he cooperating lingers. This sleeve' is limited in its downward movement by a suitable ycollar 14 adjustably mounted on the standard 12. This sleeve 1,3l carries upperand lower. annularl plates 15 which are providedV with a plu'.- rality of radial recesses in radial alinement with the pairs of sizing and shaping lingers A plurality 'of operating arms are indicated at 16 which have the inner ends pivotally mounted-in the recesses of the upper annular plate 15 whilevthe outer en'ds are bifurcated as at 1-7 ,formreceiving Lthe ends of the inner shaping lingers 5 to which they are pivotally secured as indicated at 18. Any length operating armv 16 may be used 90 for producing the desired'set ol theflingers for the making oit' rings of a predetermined size.' Similar operating arms 19'are pivotally connected inthe recesses of the lower` collar member while the free endsare bifurcated to receivethe vlower ends ,of theV shaping members `6 to. which they are'connected as indicated at 20. f

From vthe above description and .with relthatin theupward sliding movement of the sleeve 13 vonthe upright 12-that the operating arms .16 and 19 will be operated to move the shaping lingers 6 and 7'inwardl'y andv outwardly, respectively. so lthat they 105 will be moved away fromV eachu other.VJ

When the lingers are separated as a result of a movement ot the parts as above set forth, la composite ring or grommet which it is desired to size and shape may be inserted between the pairs ot shaping lingers and 'upon the downward movement ot the sleeve 13 on the upright 12, the members 5 and 6 will be moved toward each other so as to engage the laminations oit the ring and through the plurality ot radially movable pairs of lingers as illustrated in Fig. 1, it will be seen that the proper size and shape will be transmitted to the composito ring member mounted between the said shaping members. A plurality of suitable forms of clamps 2l are then applied to the ring member 22, which has been properly sized and shape-d, and which are accommodated in the recesses 9 of the plate member. rlhese clamping members are secured tightly upon the laminations ot the ring and hold the same in adjustable and shaped relation so that the sizing and shaping members may be moved out ol' engagement with the ring to permit the removal thereof from the machine for further treatment.

An operating arm 23 is pivotally mounted on the lower side ot' the plate member intermediate its ends at 211 and is provided with a pin and slot connection 25 at one end with the sleeve 13 while the opposite end forms a handle whereby the sleeve may be manually and readily raised or lowered for operating the lingers. It may also be desirable to allow for freedom ot the operators hands for other uses and, for such convenience, an upright supporting arm 28 is securely positioned upon the base plate 10. livotally secured to the arm 28 is a loot operating treadle 29 disposed at right angles to the arm for pivotally supporting the ari 30 which is pivotally connected to the operating arm 23. By pressing the loot upon the treadle the sleeve may be readily raised or lowered for operating the lingers and thus allows the operators hand freedom for use as may be desired.

Slotted tooth members 26 are adjustably mounted on a plurality of the lingers 6 through the use ot the bolts 2TY which are adapted to be threaded into one Voll a plurality ot threaded openings in the linger.

'These tooth members serve to engage the top portion of a ring to be sized and hold the same tightly against the plate member.

From the above description, it will be seen that a substantially simple and novel sizing and shaping structure has been provided tor composite ring structures particularly whereinY the operating means is adjustably connected to the shaping and sizing fingers and operable so that a movement of the operating means laterally with respect to the plate member will eliect the I l l l 'movement ol' said shaping lingers 1n a pre- Leoreeo determined manner. lt is to be understood that il? desired, the arms 1G and 19 may be made adjustable and any other means for suitably and slidably mounting the shaping lingers on the plate member be provided in lieu of the means illustrated in the drawing without departing from the scope of this invention. i
